You can do 32Q plus 2 OFDM blocks as well. But who has that kind of spectrum,
we surely don’t. A 96Mhz block maybe.
But you can’t take the total at 100G and say that’s beyond your scale, you
don’t run at full saturation do you? :)
And in order to run DCAM2s you’ll have to upgrade the RSMs to
16 connectors per DCAM2 times 6 cards is 96 DS service groups in a
chassis. At ~1.2 Gbps per connector (using 32 SC-QAM DOCSIS 3.0
channels) that's ~ 100gigabits per chassis. Quite a bit above my scale ;- )
The E6k can also do DOCSIS 3.1, which we use today, though I'm not sure
what the
E6K using gen 1 DCAMs can do about 32 service groups give or take, not that
hard to get to a point with splits where you want to go past those numbers. Gen
2 DCAMs double that by going to 16 connectors compared to 8. cBR8 is less than
the E6K.
The point of node splits is to lower customers per
Aaron, I was thinking something similar. I've never once had a node
split require moving a customer to a different CMTS. Even the very old
and (relatively) low capacity 7200 VXR could serve several nodes per
line card and supported several line cards per chassis. Newer cBR8, E6k,
and the like

I'm curious...
Is it part of the DOCSIS spec that the CMTS terminates L3, or can they bridge
to IEEE 802(.3) and delegate that to some other piece of gear?
I'm unfortunately not familiar with the MSO world much
The spec allows for bridging or layer 3 but none of the major or certified
manufacturers support bridging on larger platforms. (>1000 modems)

I'm unfortunately not familiar with the MSO world much at all aside from
a little bit of L1.

We have a provisioning system (promptlink) that we use to map cable modems
to their static ip addresses. The provisioning system has a gui front end
and it sits on linux and also acts as a dhcp server, etc. This is the same
ip address that we use for cable-helper (like ip-helper on a cmts bundle

Hi,
In my previous job, we managed static IPs by implementing L2TP tunnels
between CPEs and central Juniper LNS. It wasn't very elegant (at least for
mtu, MSS clamping), but the design was done around 15 years ago :)

Yep, it's RIP. They don't support IPv6 on this either. I've been asking for
IPv6 since 2006, it's always next year.

I do not believe it is a GRE tunnel.
I have seen (Charter) and heard quite a few run RIP or some other routing
protocol on the CPE.
Though I have not seen anything specific about Comcast specifically.
